It was 2 15 min interviews back to back - one with audit, one with tax. The audit professional was nice, but Brian - the tax direction, left a horrible impression. He not only looked down on customer service experience and my lack of tax experience (for an entry level job), he also said that the people who can't hack it in tax end up in audit. So he literally talked down on all the audit people in that 15 minute session. Strangely, I got an offer from the Big 4 and all the other firms I interviewed for, but not from this firm.
